Hello and welcome.

I think you would be better served to purchase a razor from an experienced member at SRP instead of an online retailer or eBay. You can find something inexpensive with the knowledge that it came from someone who knows what they are doing. It will also give you a low cost entry point into straight shaving which lessens the pain you will feel when you roll the edge on your first blade while you are learning to strop.

This is also why some folks will tell you to buy two cheap razors when first starting out. You will still be able to shave with the second while the first is being re-honed.
